Creamer comprising vegetable lipids and allulose

ABSTRACT

The present application relates to creamer comprising vegetable lipids, casein, maltose, phosphates, and allulose.

TECHNICAL FIELD

The present application relates to creamer containing vegetable lipid and allulose.

BACKGROUND ART

Coffee or tea (e.g., green tea, black tea, oolong tea, etc.) have strong bitter and sour tastes and are thus often supplemented with milk cream having an animal fat content of about 10-20% to reduce the bitter and sour tastes. However, milk cream is high in price, and thus liquid or powder type creamer containing low-cost vegetable lipid is commercially available. Although coffee itself has almost no calories, general coffee mix products containing commercially available creamer have a fat content of about 3 g per 1 bag (about 12 g), which corresponds to 25 kcal.

Allulose (D-psicose) is a C-3 epimer of D-fructose, which is a natural saccharide present in very small amounts in commercial mixtures of D-glucose and D-fructose obtained from hydrolysis of sucrose or isomerization of D-glucose. This was recognized as a Generally Recognized As Safe (GRAS) material by the United States Department of Agriculture (USDA). Since allulose is not metabolized in the human body, it has almost no calories. Allulose has 70% of sweetness compared to sugar and thus can be used as a sweetener to replace sugar. Therefore, the development of allulose is being actively carried out. Recently, it has been reported that allulose affects lipid metabolism (Yasuo nagata et al., J. Agric, Food Chem. 2015, 63, 3168-3176), however, the effects of allulose in association with the decrease in absorption and excretion of vegetable lipid have not been reported.

As such, the present inventors have confirmed that allulose has the effect of excreting the vegetable lipid in creamer as feces thereby completing the present application.

MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present application will be described in more detail to allow for a clearer understanding of the present application. However, the following examples are provided for easier understanding of the present application, and the present application is not limited to the following examples.

Experimental Methods

1. Breeding of Experimental Animals

16 C57BL/6J mice (male, 4-week-old) were purchased from the Jackson Laboratory (USA) and used. The mice were allowed to adapt to the breeding environment with the lab-chow diet (Purina Co., USA) for 4 weeks. Then, the mice were divided, by using the randomized block design, into a negative control group (PR: 8 mice), in which allulose was not fed, and an experimental group (PRA: 8 mice), in which allulose was fed, and the mice were fed with diet for 8 weeks.

For the diet of the negative control group, AIN-76 diet and HFD were applied, in which creamer [“Prima”, Dongsuh Foods Corporation, Korea; raw materials: 30-38 wt % of hydrogenated vegetable lipid (hydrogenated coconut oil, hydrogenated palm oil), starch syrup (including maltose), sodium caseinate, potassium phosphate dibasic, calcium phosphate tribasic] was used as the vegetable lipid. For the diet of the experimental group, 5 wt % of sugar among the components of the diet of the negative control group were replaced with allulose (crystal allulose, 98 wt % or higher of allulose based on dry solid content, CJ Cheiljedang) and used (Table 1). All animal experiments were conducted with the approval of the Ethical Commission for Animal Experimentation, Kyungpook National University (Approval No.: KNU-2013-18).

Pair feeding was performed based on the experimental group so as to feed the same level of iso-energetic diet, and thereby the effect of calorie reduction by allulose was excluded. The diet was refrigerated at 4° C. during the breeding period. The mice were bred in individual cages under constant temperature (25±2° C.), constant humidity (50±5%), and dark-light cycles at 12 hour intervals.

2. Measurement of Dietary Intake and Body Weight

Dietary intake was measured at constant time every day, and body weight was measured at constant time every week.

3. Collection and Analysis of Fecal Samples

3-1. Collection of Fecal Samples

The feces were collected for 84 hours (3.5 days) after termination of the breeding, dried, and stored frozen.

3-2. Extraction of Fecal Lipid

The neutral lipid, cholesterol, and free fatty acids in the feces were extracted by modifying/remedying the method of Folch et al. (1957). Specifically, the dried feces were ground in a mortar and 0.5 g was collected therefrom. 5 mL of a chloroform:methanol (2:1, v/v) solution was then added thereto and lipid were extracted at 4° C. for 24 hours. The extract was centrifuged at 3000×g at 4° C. for 10 minutes, and then 3 mL of the supernatant was collected, dried under nitrogen gas at 37° C., and dissolved again in 1 mL of the same extraction solvent.

Among them, 200 μL each were collected for the measurement of cholesterol and free fatty acids and dried again under nitrogen gas, and those for the measurement of neutral lipid and total cholesterol were dissolved in 500 μL of ethanol. Those for the measurement of free fatty acids were dissolved in 2.25 mL NaOH and the pH was adjusted to pH 2 to pH 3 by adding 1 M HCl solution thereto. At the time of quantification of total cholesterol and neutral lipid, 3 mM cholic acid (sodium salt) as an emulsifier and 0.5% Triton X-100 (for removal of turbidity that occurs at the time of color development) were mixed and used.

3-3. Quantification of Total Cholesterol in Feces

For the measurement of total cholesterol, 10 μL of the solution dissolved in ethanol (500 μL) and the emulsifier (690 μL) were mixed, and then 800 μL of a test solution (Asan Pharmaceutical kit) for measurement applying the enzyme method of Allain et al. (1974) was mixed. For quantification of both in forms of free cholesterol (FC) and cholesterol ester (CE), CE was converted to FC and fatty acid by cholesterol esterase. Among them, FC was reacted with cholesterol oxidase and converted to A⁴-cholestenone. The obtained product and H₂O₂ as a substrate were reacted with peroxidase, phenol, and 4-amino-antipyrine to obtain a red coloring material, and then the absorbance was measured at 500 nm. The measured value was quantified by comparing with the cholesterol standard curve.

3-4. Quantification of Neutral Lipid in Feces

For the measurement of neutral lipid, 10 μL of the solution dissolved in ethanol (500 μL) and the emulsifier (690 μL) were mixed, and then 800 μL of the test solution (Asan pharmaceutical kit) applying the enzyme method of McGowan et al. (1983) was mixed. Neutral lipid were decomposed by lipoprotein lipase (LPL) into glycerol and fatty acid. Among the decomposed products, glycerol forms L-α-glycerol phosphate by the action of ATP and glycerol kinase (GK), and this reacted with O₂ and glycerophosphate oxidase (GPO) to generate H₂O₂. Then, peroxidase and 4-amino-antipyran were treated thereto so as to develop a red color, and the absorbance was measured at 550 nm and the measured value was quantified by comparing with the standard curve of glycerol.

3-5. Quantification of Free Fatty Acids in Feces

The concentration of free fatty acids was measured using a test solution for the measurement of free fatty acids (non-esterified fatty acid; NEFA kit, Wako, Japan) according to the principle of color development using the enzyme method. First, acyl coenzyme A synthase was acted on plasma free fatty acids and thereby producing acyl-CoA, AMP, and pyrophosphoric acid. Then, acyl coenzyme A oxidase was added thereto and thereby producing 2,3-trans-enolyl-CoA and H₂O₂. This was treated with peroxidase, 4-aminoantipyrine, and 1V-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine to develop a red color, and then the absorbance was measured at 546 nm and the measured value was quantified by comparing with the standard curve of free fatty acids.

Results of Experiments

1. Confirmation of Inhibitory Effect Against Weight Gain by Allulose

At the time point of 0 week of the diet, the body weight of the negative control group (PR) and the experimental group (PRA) were at a similar level (Table 2). However, after 8 weeks of the diet, the body weight of the negative control group was significantly increased from week 1, whereas the body weight of the experimental group was significantly inhibited from the 1st week of the diet, and the significant inhibitory effect against weight gain in the experimental group was confirmed (Table 2 and FIG. 1).

2. Confirmation of Excretion Effect of Lipid in Creamer by Allulose

The effect of excretion of the lipid in creamer by allulose was confirmed by the amount of lipid excretion in the feces.

As a result, it was confirmed that the amounts of triglycerides and free fatty acids in the feces significantly increased in the experimental group compared to the negative control group. In particular, it was confirmed that the amount of free fatty acids was significantly higher than that of the negative control group (Table 3 and FIG. 2).

A significant difference was shown between PR and PRA: *p < 0.05, ***p < 0.001. PRA, HFD + creamer + 5% allulose; PR, HFD + creamer

Accordingly, it was confirmed that when allulose was ingested along with the vegetable lipid in creamer, the excretion of lipid as feces was promoted.
